Title: Method and apparatus for joining sheet or ribbon formed flows in a coextrusion process
Inventor: RASMUSSEN OLE-BENDT
IPC: B29C48/49
Filed: 2001-04-11
Granted: 2007-09-18
Abstract: A method and apparatus are described for coextruding two materials A and B, in which B is extruded on A  through a port (3), in which the separating wall between the flows of A and B is formed as a flap closure (4) adapted to act as a non-return valve for the flow of B into A, and further means are provided for extruding B through the port in pulses. The pulses may be effected by opening and closing the closure, by mechanical transmission means or by the effect of imposing pressure difference on the flap (4) by the flows of A and/or B. The pulsing means preferably involves rams (1).  The invention is particularly suitable for extruding a low viscosity material B onto a higher viscosity material A, or for making sheets or pipes with alternating segments of differential flexibility, or for coextruding a flow of solid particles with a flow of liquid.

Abstract: A fixed blade air mixing apparatus includes a plurality of radially extending vanes which extend away from a common center and terminate at their outer ends within a polygonal shaped shroud. The plurality of vanes include an inner section which is curved or pitched in one direction, and an outer section which is curved or pitched in a second direction away from the inner section, the inner and outer sections sharing a common leading edge. The apparatus is intended for use in eliminating stratification of airstreams of different temperatures flowing through a common passage, for example, in heating, air conditioning, or other ventilating ducts. The vanes are designed to establish downstream turbulence of the airstreams passing therethrough which produces optimum mixing effectiveness and a uniform velocity profile of the air downstream of the mixing apparatus with a minimum pressure drop as the air flows through the apparatus.

Title: A food supplement containing essential fatty acids and products therefrom
Inventor: STEWART JAMES F
IPC: A23L13/40
Filed: 2002-04-23
Granted: 2007-03-13
Abstract: This invention describes feed supplement, and processes which increase the amount of essential fatty acids in the milk, eggs, meat and other by-products from animals including dairy cattle, beef cattle, goats and poultry. The food supplement described herein includes specific fish meal, fish oil, algae or plant dietary supplements combined with a natural ingredient/coating mixture, which can be either talc, clay or combinations; or mixtures of talc or clay with flax sprout powder to achieve enhanced levels of the essential fatty acids in the milk, eggs, meat and processed livestock products from animals fed this dietary supplement. In ruminants, the natural ingredient/coating mixture prevents microbial degradation of the essential fatty acids in the rumen stomach of the animals fed with this composition, thus providing more of the essential fatty acids to the animal, for their use. This in turn results in improved concentrations in the milk, meat and processed products from these animals. Poultry fed with this food supplement also have a higher concentration of essential fatty acids in their eggs and meat.
